COTTON-GIN.

SPECIFICATION forming part of Letters Patent No. 356,463, dated January25, 1887.

' Application iiled March 30, 1886. Serial No. 197,172. (No model.)

To all whom, it may concern.-

,Be it known that I, DANIEL W. GASKILL, a citizen of the United States,residing at Little Rock, in the county of Pulaski and State of Arkansas,have invented certain new and useful Improvements in Cotton-Gins, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to devices for ginning seed-cotton, in which arevolving rollcarrier is used to bring the cotton to the saws; and theobject of my invention isto improve cotton gins in the particularshereinafter I accomplish this object by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a transverse section of aportion of a cotton-gin constructed in accordance with my invention.Fig. 2 is a longitudinal vertical section of the saws and saw-spacingblocks with a portion of the breastplate and its adjustable shoe. Fig. 3is a transverse vertical section of the breast-plate and shoe. Fig. 4 isa transverse section on a large scale of one of the serrated wing-platesand arms of the roll-' carrier. Fig. 5 is a front view of a portion ofone of the serrated wing-plates.

In the drawings, A represents a portion of the frame of the gin, uponwhich is mounted, in suitable bearings, the shaft B, carrying the sawsB, each provided with a central eye, I), and in the spaces between thesaws are mounted upon the shaft a series of cylindrical parting-blocks,B, the peripheries of which extend to the roots of the saw-teeth, toprevent the passage of cotton-seed forward between said saws, as will behereinafter described.

The usual ribs between the saws are dispensed with, and in place of themthere is adjustably attached to the breast-plate C a long plate or shoe,0. This shoe has slots 0 opposite each saw, and above said slots theshoe has shallow grooves 0 having their sides slightly divergent upwardand their bottoms even with the lower edge of the breast-plate, so as tofacilitate the clearance of the seeds from in front of the saws. Thespace between the bottom of the shoe and the partingblocks B is aboutone-twelfth of an inch, and the space between the bottoms of the slots0' and the teeth of the saws is about the same, and

this space, running the whole length of the gin, permits all the lint topass through,while the seed is kept back and revolved within the hopperA until all the lint is taken off, and then they drop out at A Thebreast-plate O is slotted at the points where it receives the screws 0,which secure it adjustably to the frame of the gin, and it is alsoslotted where it receives the screws G which adj ustably secure the shoethereto.

The cotton is revolved within the hopper by the roll-carrier D. This hasa series of radial arms, cl, secured to its periphery, and to the outerends of said arms are removably attached the serrated plates d so thatwhen they are worn out new plates can promptly. take their place. Thegrooves between the teeth of the serrated plates d are beveled at (2toward their base, to make a lodgement for the cottonseed; or theirfront edges are made more prominent, so that the teeth will easily carrythe seeds away from the shoe and drop them at A. To regulate the amountof cotton operated upon at once by the saws, and consequently the amountbearing upon the saws and parting-blocks, there is between theseed-chute A and the saws a segmental slide or cutoff, E, the ends ofwhich fit loosely into grooves a*, formed in the ends of the casing.This slide is provided with a segmental rack, E, into which meshes asegmental pinion or pinions, f, pivoted to the frame at f,and operatedby a handle, f, projecting therefrom.

Having now fully described my invention, I claim I 1. The combination ofthe ginsaws, each provided with a central eye, parting-blocks extendingto the bases of the teeth of said saws, and a breast-plate provided withan adjustable shoe having its lower edge above the bases of thesaw-teeth and grooves for each saw, substantially as and for the purposedescribed.

2. The combination of the gin-saws, parting-blocks extending to theteeth of said saws, a breast-plate, and an adjustable shoe thereon, witha roll-carrier having radial arms with detachable plates havingrearwardly-recessed teeth, substantially as and for the purposedescribed.

3. A cottongin comprising the gin-saws,

plate and shoe, an adjustable segmental. slide, IO

the segmental rack, and the pinion, substantially as and for the purposedescribed.

In testimony whereof I affix my signature in presence of two witnesses.
